[V8] back-up light switch

[Tony and Lillie]

Kent,

For the starter circuit, Here's what I can interpret.
The only connection to the trans circuit is through the alarm system, it's
the ground for switching the starter/interlock relay (number 8). It's
connected to the multi function switch via a green wire, from terminal 1/50W
on the switch. This is connected to a brown/white wire on terminal 2/50,
which is a ground Feed. The circuit is completed when the shifter is in Park
or Neutral. So, you will need to jumper the brown/white wire to the green
wire, and this basically bypasses the MFS altogether.

This part of it allows you to completely bypass the start portion of the 
MFS. However, to make it simpler, I'd find the starter relay under the dash 
and jump it instead. Test it to make sure it works, then that's one liss 
thing you have to modify. I don't have the schematics for the 5-speed, but I 
know this is in fact how Audi did it on all the other manual cars of that 
era. No relay in that position, just a small "Z" metal strip.
